Mar, 28 1911 Anne-em nu am" a. me you n Be it known that I, Woman J. Kenna, a citizen of the United States, and residing in the townshi Fayette and State of ennsylvania, invented or discoverednew and useful Improvements in- Coke-Ovens, of which the following is a specification.

Myinvention relates to coke-ovals; and simi ar devices, and consists in new and improved means for conserving and leading of the aseoua producte of combustion for use in t generation of steam and for other purposes.

-I provide means for regulating the flow of gas through the discharge patcag'e, so that when the oven is being charged or 'drawn, the entrance of cold air into said paesa e is prevented. I also'provide means for a ding tothe gas flowing through said passage quantity of air as may berequired for its proper combustion.- i I- also provide new and improved means for preventing the burning out or disintegration of the trunnel-head of the oven, the gas passage and adjacent rtione of the oven structure, consistin leading from the'front o the oven and communioating with. other air-chambers surrounding the trunnel head and beneath the floor of the gas passage. These elements are so constructed and arranged that a constant current of air or other cooling medium Y is maintained therethrough. =The air-pas- 'sa'ge is preferably constructed to incline inwardly and u wardly to facilitate .the cm -trance of air. rom outside.

In the accompanying drawings, Figure 1 is a longitudinal section of a bee-hive coke oven fitted with my invention; Fi 2 is ,a horizontal section alone the line I -II in Fig. 1}; Fi 3 a similar section along the line IIL- II in' Fig. 1; Fig. 4 is a vertical,

.section along the line IV-IV in Fig. 1; Fig. 5 is; a similar section along the line V--V in Fig. 1,-and 6 is a-detail vertical section similar to Fig. I and showing a modification of the trunn e l -head construcsame tion.*- a

-The' following is a detailed description of the drawings, which are; however, merelyillustrative of a practical embodiment of my invention and not intended to limit the to theexact structure shown I x I have-illustrated my invent on urmmiec- :tion with the ordinary bee-h ve type. of

Thetop of an: 52 is composed of tier/i655 of thick tile 8--8, against the end of the for ward lllejlf which series the tile 0! Plait 7 abuts when in place to clone opening 3.

99 are vertical groovea in the inner faces of the side walls of passage 5 just in Id vanrae of the forward tile 8, so that, when it? is desired to cut on the passage 5 to prevent;

the-passageof cold air through said flue. when, fo inatnnce, the oven is being drawn,

all that required is to slide the tile 'Yfor wardly a short distance and insert a tile 16- tom of aaidcha mber 19. The chamber 12 in turn discharges into a chamber 13 which is located beneath the floor of flue 5. To

cause a lateral circulation of the cooling Inc through chamber 13, I staggered battles in said from the side wall;

dium while pansin provide a series 0 chamber extending from top bottom of the 14-44, extend the botchamber and serve also to sup nort tom tile oi the flue 5, which tg ber beneath said the top of said passage v cooling chamber.

extend the full width of the flue. At the rear of chamber 13, the

cooling medium passes to alateral flue 15 which extends beyond the plane offiue 5 and discharges into a vertical chimney or stack 16 which carries oil the heat-ed air at an elevation to promote the draft. I prefer to incline the passage 11 fromthe-front upwardly toward-the rear to facilitate the draft. The chamber 13 may also be inclined in the same direction and for the samepurposer I prefer also to provide means for admitting 'air, when desired to promote combustion, of the gas; into the fine 5 by means of a port 17 which, when not in use, may be closed bf a removable tile:

I find that the use of a relatively thick tile for the top of passage 5 is a positive advantage over the usual practice of bricking and covering the same with a thick layer of earth. The latter method results in binning out the top of the flue but the-thick tile, without an earth covering, radiate enough of the heat to prevent injury fully cooling the gas in the flue.

I have shown a slight modificato the tile without harm- .In Fig. 6 tion wherein the trunnel-head openin is inclined so that the increment of tile 1n opening the trunnel head isfa'cilitatedJ My invention can be applied to any cokeoven at ices e' qp ense than t rat of constructing the usual gasp assages and the arrangement of cooling means i;prolongs the life of the structure indefinitely.

What I desire to claim is 1. Ina coke-oven, a gas flue communioning with the trunnel-head, a cooling ch.am-

leading from the frpnt of the-oven into said 2. In a coke-even, a'gas flue communicab ing with the trunn'el head a chamber befiue; and an air-passage J ing chamber,

n'eath said flue, means for introducing a cooling medium into said chamber from the vfront of the oven and withdrawing said cooling medium at the rear of the oven.

3. In a coke-oven, a gas flue communicating with the trunnel'head, a cooling chamber surrounding said trunnel head below said flue, an upwardly inclined passage leading from the front of said oven into said cooling chamber, a second cooling chamber beneath said fiue' communicating with said first cooland an outlet flue at the rear of said second cooling chamber.
